MACHINE FOR OPERATING UPON SOLES.

7 Application filed December 1 The present invention-,relatesto machines for'operating upon sole. blanks, and more particularly to an automatic 111%1Cl11I1G fI' simultaneously rounding, randing and inking the edge face of a channeled, welted, Mc- Kay outsole prior to sole laying.

The object of the present invention 1s to produce an automaticmachine in which the Operation of trimming and the operation of randing and the operation of inking the outsole edge face are simultaneously performed prior to the sole laying operation, as distinguished from the usual practlce of performing these operations" consecutively and by manipulations after the outsole has been appliedto the shoe, and to automatically perform these operations w1th best results, it is necessary to do so prior to sole laying, as herein proposed.

To the accomplishment of this object, and such others as may hereinafter appear, the features of theinvention relaterto certain devices, combination and arrangements of parts, hereinafter described and then set forth broadly and in detail in the appended claims, which possess advantages which will be apparent to those skilled in the art.

The various. features of the present nvention will. be best understood from an inspection of the accompanying drawings, illustrating the best form of the invention at present devised, in which,

The features of the present invention are embodied. in an automatic.sole-rounding machine which is provided with a pattern upon which the outsole rests, 310131111) which presses upon the opposite plane surface of the outsole, holds it in position uponthe pattern, and a' knifewhich darts around the peripheral edgeofthe stationary-pat tern, cuts the'outsole to the shape of the pattern. The'machine to which. my invention is applied: is disclosed in the patent to Julian, No. 11,501, reissued July' 2,1895.

The machine disclosed in the aforesaid patent has since been improved by the addition offarebound mechanism which causes the l n1fe,after1t has completed its traverse around the pattern, to, first travel beyond the initial'starting point and then to return and stop atabout its initial starting position and such improvementis embodied, of course, in

thecommercial Julian sole' rounder.

Referring firstto Figs. 1, 2 and 3 the work operated upon by the machine embodying thefeatures of the present invention, comprises achanneled and welted McKay outsole ,llhaving one face thereof provided with a feather 12, a shoulder 13, and a shoulder. lip 14: turned back and down upon.

the channeled face of theoutsole. 'lheother face of the outsole is provided with a beveled welt 15 which is secured to the unchannelefd face of theoutsole by stitches 16 anchored on the welt 1.) and feather 12, respectively, as in the usual practice after the McKay; outsole has been died out from a blank to the form of a shoe outsole preparatory to sole laying but, in connectlon with nay present invention, without being mould- ThelMcKay outsole is inserted into the machineillustrated.in Fig.6, which is a.

regu ar Julian solerounder such as' disclosed in the Julian patent hereinbefore referred to but modified to include the regular commercial rebound mechanism.

In order to support a channeled, welted hilcKay outsole, the pattern 17 (Figs. t and (3) is provided with a beveled strip 18 arranged with one face in contact with the supporting face of the pattern. The op posite face 19 of the stripis beveled to engage the feather 12 of the channeled,

welted McKay outsole. One edge face, the face 20, of the strip 18, is arranged flush with the peripheral edge face 21 of the pat tern. The opposite edge face, the face 22, of thestrip 18 is constructed and arranged to engage the shoulder 18 of the outsole. After mounting the outsole on the pattern 17, in the manner illustrated in Figs. 8 and 9, the clamp 23 (Figs. 5 and 6) is actuated to cause its peripheral edge 23" (Figs. 8 and 9) to engage'the welt15 and hold the outsole on the pattern 17. l

The machine is then thrown into opera tion whereupon theknife 24 (Fig. 9) darts around the pattern and Sil'llllltilllQOHSlY cuts the edge face of the outsole to the shape of the pattern and rands the peripheral top edge of the welt 15, or the top edge of'the sole when thewelt is omitted, and, as the term rand implies, on a bevel extending over the marginal portion of the sole.

In order to simultaneously ink the face ofthe ontsole cut by the knife 24, the knife lever or support 25 (Fig. 7) carries a stud 26 upon which an arm 27 is pivoted. The arm 27-carries an ink reservoir 28 and a roll 29 mounted to rotate Within the reservoir. The roll 29 is of felt and rotates within the reservoir with a portion of its peripheral portion projecting therefrom in contact with the cut face of the outsole edge. In order to prevent leakage, the roll 29 is scraped by an edge 30 on the ink reservoir 28 and also by an edge 31 formed on a leaf spring 32 secured to an exterior wall of the reservoir llheroll 29 is held against the cut edge face of the outsole by a spring 33, coiled about the stud 26, one end'of'whieh is secured to the knife support 25 and the other end of which is engaged with the arm 27.

It is to he noted that for positioning with absolute iuiiformity a given number of soles in the machine, nicks a, and Z), are made at the sides of the heel portion (preferably by thedies used in conjunction with dieing out machines) and the pattern 17 is provided with sole holding projections a, and b, at the sides of the heel portion, which correspond as to location and form to the nicks onthe sole. Thus a given number of soles will be positively uniformly set relatively to the periphery of the pattern and sequenmay 17% applied uniformly to shoes at sole lagging. Proceeding further towards obtaminguniformity at sole laying and facililating the sole laying operation, the clamp is provided at its inside ball portion and at its toe-end with projections c, and cl, located at a substantial distance from its edge to thereby predetermine the sole extension at sole laying by indentations on the welt strip on the sole (or on the sole proper when no welt strip is provided) so that the sole layer will readily lay the marked soles on the shoes with absolute uniformity.

It is to be further noted that, as hereinbefore stated, the outsoles are not moulded and,althoiigh a desirable feature in itself, moulding is not absolutely necessary, as the sole laying operation can include the lay ing of the outsoles by the operator of the.

sole fastening-machine employed in solo laying.

it is to be appreciated that although a welted McKay outsole is herein shown, the invention and the application therefor is intended to cover and does cover the pro- 'isi on of any other type of outsole adapted to the practice of my invention and the appended claims are to be interpreted in this broad sense.
